HOT-f-WATER GENERATOR.

SPECIFICATION forming part of Letters Patent No. 407,878, dated July 30, 1889.

To all whom t may concern:

Be it known that I, PETER G. VAN WIE, a citizen of the United States, and a resident ot' Cleveland, county of Cuyahoga, and State of Ohio, have invented certain new and useful Improvements in Hot-Tater Generators, of'

which the following is a specification, the principle of the invention being herein eX- plained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention has for its objects, first, a hot-water generator provided with a nonradiating jacket inclosing the reservoir and conforming in shape thereto, whereby the heat arising from the burner is conserved and forced into close contact with the reservoir on its outward passage; second, a peculiar form of reservoir adapted to economically and rapidly heat the water; third, a peculiar formation of generator whereby the waste heat and gases on their outward passage are brought into contact with the supply-pipe, and thereby raise the temperature of the water entering the reservoir; fourth, valve mechanism intermediate ot the generator and the boiler, whereby water may be drawn direct from the generator, if desired, the valve being so constructed as to afford free vent for the water at all times from the reservoir.

Referring to the drawings, Figure l is a central longitudinal vertical section of the generator. Fig. 2 is a transverse vertical section of the generator, taken at right angles to Fig. l. Fig. 3 is a horizontal longitudinal section of the generator. Fig. at isa detail view of the mixing-chamber air-valve. Fig. 5 is a detail view of the two-way valve.

The generator is formed in two sections or portions, respectively, a a', a cone-shaped reservoir B being vertically secured in any suitable manner in the central portion of section d, said reservoir being formed with an opening or deep depression b in its base of cone-frustum shape. An annular depending water-leg b constitutes the lower portion of said reservoir and incloses or forms the wall of the opening b. The upper portion b3 of said reservoir is formed as a continuous chamber in horizontal plane. Pipe C leads from said reservoir to the usual form of boiler C. Located in said pipe and intermediate of the Application tiled November 7, 1888. Serial No. 290,202. (No model.)

reservoir and boiler is the two-way valve c, provided with the straight-way opening c and transverse opening c2, formed at right angles to said first opening and extending more quickly than the greater amount contained in the boiler, and this intermediate faucet renders it available.

By means of the engagement of shoulders d and CZ the valve is prevented from being moved to any position where there is not free course or vent for the water passing from the reservoir that is, the valve at all times permits the water to flow either into the boiler or out of the faucet and is and can be at no time confined within the generator, and hence all danger or possibility of explosion within the reservoir is prevented.

NVithin the generator is secured the sheetmetal cone or shaper E, that incloses the reservoir, and is used as a form' or Shaper, the

space intermediate of said shaper and the wall of the generator being illed with the non-conductin g and nonradiating packing or jacket E', that may be made of mineral wool or other similar substance, whereby the heat is conserved, and, as the cone conforms in shape to the generator, the heat arising from the burner is compelled to pass close to the generator, and is thus utilized without waste. Said cone is provided at its upper portion with the vent c, that connects with the opening e in the partition @.3 of the generator. At its lower portion the cone extends down about to a level with the top of the burner and is secured to the generator-wall. Flue E2 is formed intermediate of said shaper and the reservoir, the lower part of said flue of shape substantially a counterpart to said reservoir, said iiue having outletfthrough the vent e.

Two transverse heat-outlet openings f are IOO formed in the generator near the top of the Water-leg and pass through the latter, affording means of escape fo the hot air within the generator-base, preventing any packing and deadening of said air and allowing free and rapid circulation. Said heat-outlet openings or cross-flues f connect the interior central opening b with said flue E2 in a crosssectional plane passing through the upper portion of said water-leg b.

Cold-water-supply pipe H enters section u is given three several turns vertically up and down in said section, and passes thence through section-wall e3 and connects with the bottom of the reservoir, opening into the same. As the heated air issues through opening e it passes down around the coils of pipe H and thence under partition J, up flue K,

` and out of vent e2, thus utilizing the waste heat to raise the temperature of the waterbefore entering the reservoir. Y

The foregoing description and accompanying drawings set forth in detail mechanism in embodiment of myinvention. Change may be made therein provided the principles of construction respectively recited in the following claims are employed. I therefore particularly point out and distinctly claim as my inventionl. In a water-heater, the combination, with Water-reservoir B, .having its lower portion h made in conical ring form and having its upper portion h3 made as a continuous chamber in horizontal plane,-of the ue E2, surroundving said reservoir, the lower portions of said flue E2 being open and located substantially in the saine horizontal plane with the bottom` vertical outlet-pipe b2, connecting with the central upper extremity of said central reservoir portion h3, of iue E2, surrounding said reservoir and connecting portion o f said pipe b2, and said water-leg h', having upper crosssectional portion provided with one or more cross-cutting fluesf, connecting the upper portion of the central conical depression Z) with said iiue E2, substantially as set forth.

3. In a water-heater, the combination, with cone-shaped reservoir B and jacket E, of non-radiating material, located intermediate 0f the reservoir and the outer wall of the heater, of flue E2, formed intermediate of. said jacket and the reservoir, said jacket inclosing said reservoir on the top and sides, substantially as set forth.

4. In a water-heater, the combination of cone-shaped reservoir B, provided with depending annular water-leg b', vertical outletpipe b2, connecting with said reservoir, jacket E', formed intermediate of the stove-wall and the reservoir, said jacket inclosing said reservoir on the top and sides and surrounding said discharge-pipe b2, the interior shape of said jacket and the exterior 'shape of said reservoir where lying in the same horizontal plane being substantially in counterpart of each other, and iiue E2, being formed intermediate of the jacket andthe reservoir, whereby the products of combustion are caused to pass close to the reservoir, and are kept in contact with the same, substantially as set forth.

5. In a water-heater, the combination of cone-shaped reservoir B, shaper E, having its body portion of conical form and provided with the outlet-flue e, located above the top of the reservoir, and mineral-wool jacket E', intermediate of the shaper and the outer wall of the heatensaid jacket inelosing said reservoir at top and sides, substantially as set forth.

In testimony that I claim the foregoing to be my invention I have hereunto set my hand this 2d day of November, A. D. 1888.
